10 Pack - 3 Inch Unitized Quick Change Discs 2SF S/C Fine Polishing Type R Roloc

Unitized wheels feature compressed, and cured layers of non-woven nylon fibers impregnated with abrasive grains. The structure of these unitized wheels allows for bi-directional use (they can be run in either direction), reduced loading, and minimal heat buildup which extends the life of the disc and protects the work piece.
